A lithium battery battery box with automatic fire extinguishing and explosion-proof function

Abstract

The invention relates to a lithium battery battery box with automatic fire-extinguishing and explosion-proof function, which belongs to the field of fire-proof and explosion-proof lithium batteries, and solves the problem that the lithium battery ignites and explodes due to thermal runaway in the existing lithium battery technology; the solution includes a battery box shell and a lithium battery device and a trigger pump installed in the battery case, the lithium battery device includes a plurality of groups of lithium battery mechanisms, and the lithium battery mechanism includes a shell group, an upper trigger member arranged on the top of the shell group, and a lower trigger member arranged at the bottom of the shell group. The component, the lithium battery unit disposed inside the shell group, the upper trigger component is used to be triggered and communicated with the trigger pump when the temperature of the lithium battery unit reaches the preset temperature value. When the component is triggered and communicated with the trigger pump, water flows into the shell group through the upper trigger component to achieve fire and explosion protection for the lithium battery cell, and the lower trigger component is used to be triggered to drain out when the shell group is filled with water.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to the field of fire-proof and explosion-proof lithium batteries, and in particular to a lithium-battery battery box with automatic fire-extinguishing and explosion-proof functions. Background technique [0002] During the use of the existing lithium battery pack, the main cause of fire and explosion is the so-called thermal runaway caused by short circuit, poor heat dissipation caused by overcharging or high ambient temperature, that is to say, when the lithium battery cell is When the surrounding environment reaches a critical point, fire will occur, and after a period of time, the fire will cause the lithium battery cell to explode. Therefore, the present invention provides a lithium battery battery box with automatic fire extinguishing and explosion-proof function. SUMMARY OF THE INVENTION [0003] In order to solve the problems mentioned in the above background, the present i...
